YAMAL 402 was supposed to maneuver itself into a circular geosynchronous orbit 22,300 miles (35,888 km) up and lowering inclination where it can match Earth's rotation and appear parked over the equator at 55 degrees East longitude to begin a 15-year service life. However the upper stage of the heavy-lift Proton rocket failed to perform the full duration of its final boost-burn, leaving YAMAL 402 in a lower-than-planned orbit at the end of a 9-hour flight from the Baikonur Cosmodrome.
